[0025] The present application provides an electronic cigarette oil capable of improving the smoking taste. The electronic cigarette oil comprises the following components, calculated by weight percentage: nicotine, ellagic acid, elderberry extract, coix seed extract, essence, and solvent.

[0026] Nicotine, as the main ingredient in e-liquid, can provide smokers with the satisfaction they need while helping to maintain the stability of the e-liquid;

[0027] Ellagic acid is a natural polyphenol dilactone widely present in various nuts and soft fruit plant tissues, with excellent anti-mutagenic, anti-cancer and antioxidant effects; the ellagic acid of this application can be purchased from Guangdong Wengjiang Chemical Reagent Co., Ltd.

[0028] Elderberry is rich in bioactive ingredients and nutrients. Among them, the most important bioactive ingredients are polyphenols and cyanogenic glycosides. The nutrients and other ingredients are mainly vitamins, minerals, amino acids, etc. Identifiable substances include vitamin A, vitamin C, iron and phosphorus, with a sour and irritating feeling. The elderberry extract of this application can be purchased from Fufeng Snot Biotechnology Co., Ltd., or conventional extraction methods can be used, such as ethanol extraction, macroporous resin purification, supercritical extraction, etc. Those skilled in the art can purchase or extract according to actual conditions, and this application is not limited here.

[0029] Coix seed, also known as Job's tears, is cool in nature and sweet in taste. It is rich in protein, fat, vitamins, minerals, and carbohydrates. The active ingredient in coix seed extract is primarily coix seed oil, which is a neutral lipid. Modern pharmacological studies on coix seed oil have shown that low concentrations of coix seed oil have an excitatory effect on the isolated heart, intestine, uterus, skeletal muscle, and motor nerve endings, while high concentrations have a paralyzing effect. The coix seed extract used in this application can be purchased from Sanyuan Tianyu Biological Products Co., Ltd.

[0030] The primary function of flavors is to provide a variety of inhalation flavors and enhance the mouthfeel of the e-liquid. Flavors can mask the taste of nicotine or other chemicals, making the e-liquid taste more natural and pleasant. Secondly, flavors can improve the antioxidant properties of e-liquid and extend its shelf life. Furthermore, some flavors have health and medical benefits, such as antibacterial, antiviral, and anti-inflammatory properties, which can enhance the health and medical benefits of e-liquid. Those skilled in the art can add a variety of flavors based on actual needs, and this application does not limit the specific content of each flavor in the e-liquid.

[0031] The solvent is used to dissolve the various components in the electronic cigarette oil. The solvent can also maintain the stability of the electronic cigarette oil. Those skilled in the art can select and add the solvent from commonly used solvents.

[0032] In some embodiments, the electronic cigarette liquid comprises the following components calculated by weight percentage:

[0036] Coix seed extract 5-10%,

[0037] 7-15% flavor, and

[0038] Solvent 65-90%.

[0039] The combination of ellagic acid, elderberry extract and coix seed extract in e-cigarette oil can neutralize each other's sourness, sweetness and stimulation, produce a unique smell and taste, increase the freshness and sourness of the oil, and enhance the taste of the e-cigarette oil.

[0040] In addition, too much or too little of a certain ingredient may have a negative impact on the taste of the e-cigarette oil; for example, too much ellagic acid may make the e-cigarette oil taste too bitter; too much elderberry extract may make the e-cigarette oil taste too sour and strong; too much coix seed extract may make the e-cigarette oil taste too sweet.

[0041] In some embodiments, the flavor comprises at least one of caramel, fructose, aspartame, ethyl butyrate, ethyl lactate, raspberry ketone, L-carvone, vanillyl isobutyrate, anisaldehyde, and maltol.

[0042] Flavors can enhance the taste of e-liquid; for example, caramel and fructose can provide sweetness, aspartame can provide sweetness and improve the taste, ethyl butyrate and ethyl lactate can produce a soft fruity aroma, raspberry ketone and L-carvone can provide fruity and grassy aromas, vanillyl isobutyrate and anisaldehyde can provide spicy and fruity aromas, and maltol can enhance sweetness; these ingredients can also mask the taste of nicotine or other chemicals in e-liquid, making the taste of e-liquid more natural and pleasant.

[0043] In some embodiments, the electronic cigarette oil further comprises 0.2-5% of a cooling agent by weight.

[0044] Cooling agents can produce a cool feeling in the e-cigarette oil, increase the taste of the e-cigarette oil, and make smokers feel more comfortable and happy.

[0045] Optionally, the cooling agent is at least one of natural or synthetic compounds such as menthol, camphor, and coumarin derivatives. For example, menthol and menthone are commonly used cooling agents that can provide a refreshing taste and invigorate the mind. Camphor and coumarin derivatives can also be used to enhance the taste and aroma of e-cigarette liquids.

[0046] In some embodiments, the cooling agent includes at least one of menthol, menthone, and WS-5 (N-(ethoxycarbonylmethyl)-para-alkane-3-carboxamide); the above cooling agents have high safety and stability and can be used to increase the taste and smell of electronic cigarette oil.

[0047] In some embodiments, the electronic cigarette liquid further comprises 1-15% of fruit essential oil by weight.

[0048] Fruit essential oils have a rich aroma and fruity flavor that can enhance the taste and flavor of e-cigarette oil, making it more natural and refreshing.

[0049] In some embodiments, the fruit essential oil includes at least one of neroli essential oil, lemon essential oil, apple essential oil, watermelon essential oil, strawberry essential oil, grapefruit essential oil, passion fruit essential oil, mango essential oil, and lemongrass essential oil.

[0050] These fruit essential oils have different aromas and flavors, which can provide a more diverse taste and enjoyment for e-cigarette liquids. For example, orange blossom essential oil has a refreshing aroma that can bring a sense of relaxation and pleasure; lemon essential oil has a strong lemony aroma that can be refreshing; apple essential oil has a sweet fruity aroma that can enhance the taste and comfort of e-cigarette liquids; watermelon, strawberry, grapefruit, passion fruit, mango and other essential oils have a rich fruity flavor that can provide a fresh and sweet taste for e-cigarette liquids.

[0051] In some embodiments, the solvent comprises one or more of ethanol, propylene glycol, glycerol, glycerin, and sorbitol.

[0052] This application also proposes a method for preparing an e-cigarette liquid that enhances the taste of the e-cigarette. The method comprises heating and stirring the raw material components of any of the e-cigarette liquids described above in a proportional manner. The e-cigarette liquid prepared by the method enhances the aroma and flavor of the e-cigarette liquid and improves the taste of the e-cigarette liquid.

[0053] Unless otherwise specified, the raw materials and equipment used in this application are commonly used in this field; unless otherwise specified, the methods used in this invention are conventional methods in this field.

[0146] Electronic cigarette taste performance test: The electronic cigarette liquids obtained in the examples and comparative examples were injected into electronic cigarette devices respectively, and a sensory evaluation was performed.

[0147] The sensory evaluation method includes the following steps:

[0148] Step 1: Set five evaluation indicators, including aroma volume, aroma quality, sweetness, stimulation, and satisfaction; and assign different scores based on the degree of impact of each evaluation indicator on the sensory quality of e-cigarette liquid.

[0149] Aroma volume refers to the concentration and fullness of the aroma. The aroma volume of e-cigarettes depends on the content and ratio of flavors and fragrances in the e-liquid, the liquid conduction method of the smoking device, etc.

[0150] Fragrance quality refers to the quality of the fragrance, which includes the purity, persistence, coordination and variability of the fragrance.

[0151] Sweetness refers to the taste of sugar and honey felt during the inhalation of e-cigarettes, and the intensity of the taste can be perceived by the tongue, palate and pharyngeal mucosa.

[0152] Irritation refers to the uncomfortable feeling caused by inhaling the smoke produced by atomization of e-cigarette oil to the sensory organs including the mouth, throat and nasal cavity.

[0153] Satisfaction refers to the comprehensive feeling produced by the strength, concentration and aroma of the smoke produced by the atomization of electronic cigarette oil on the sensory organs inside the mouth and nasal cavity.

[0154] Step 2: Arrange 10 e-cigarette smokers, each with an e-cigarette liquid sensory quality evaluation form, use the secret evaluation scoring method, and adopt the overall cycle evaluation method to smoke the e-cigarette liquid. According to the meaning of the scoring values ​​of the five sensory quality evaluation indicators in Table 1, the full score for each item is 9 points, and the full score for sensory quality evaluation is 45 points. Each item is scored in 1 point units. The meaning of each score is shown in Table 1.

[0155] Table 1

[0156]

[0157] Result statistics: The evaluation results of all evaluators are valid. The arithmetic mean of the individual evaluation results of each evaluator is calculated, and the arithmetic mean of each individual item is added together to obtain the total score.

[0158] The electronic cigarette liquids prepared in the examples and the comparative examples were added to electronic cigarette devices for sensory quality evaluation. The specific evaluation results are shown in Table 2. The scores for each evaluation indicator in Table 2 are the arithmetic average of the valid scores of the 10 e-cigarette reviewers.

[0159] Table 2

[0160]

[0161] As can be seen in Table 2, the total scores of Examples 1-4 were all higher than those of Comparative Examples 1-6, indicating that the e-cigarette liquids in the Examples were superior to the e-cigarette liquids in the Comparative Examples in terms of aroma volume, aroma quality, sweetness, stimulation, and satisfaction. Specifically, this may be due to the unique aroma and mouthfeel produced by the combined use of ellagic acid, elderberry extract, and coix seed extract, as shown by the significant reduction in each of these sensations in Comparative Examples 1-4. Furthermore, the e-cigarette liquids in the Examples also achieved a good balance between sweetness and stimulation, likely due to the interaction between these components, which neutralized their respective sour, sweet, and stimulating effects. Overall, the e-cigarette liquids in the Examples were superior to the e-cigarette liquids in the Comparative Examples in terms of taste and smoking experience.

[0162] In addition, according to Comparative Examples 5-6, it can be seen that ellagic acid, elderberry extract and coix seed extract can only obtain a better smell and taste within a certain ratio range.

[0163] The various technical features of the above-described embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the various technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0164] The above-described embodiments merely represent several embodiments of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
